The invention will be hereinafter more fully described in detail, and reference will now be had to the drawings accompanying this application, wherein like numerals of reference designate corresponding parts throughout the several views, in whichdoors are provided with pivoted bars 15 15, adapted to lie within the car beneath the lowermost shelving when the doors are closed, but when open are adapted to support the doors by resting against longitudinallydisposed angle-irons 16 16, arranged upon the floor 3 of the car adjacent to the longitudinal edges thereof, as clearly illustrated in Fig. 2 of the drawings.

A cone-shaped deflector 17 is arranged centrally of the car and is carried by the lowermost shelving of said car. Extending up- IOO wardly through the bottom of the car in close proximity to the deflector is a steaminlet pipe 18, the lower end of which carries a l hose or iiexible connection 19, whereby it can be connected to a pipe-line supplied with steam from a suitable boiler, it being not necessary to illustrate the two last-mentioned elements.

In Figs. 3 and 4 of the drawings I have illustrated a slightly-modied construction wherein a rectangular frame of tubing or piping 20 is mounted within the car and supported by brackets or cleats 21 21, carried by the bottom of the car. This frame of tubing or pipes is used to thoroughly distribute the .wet steam throughout the car and between the various shelves thereof, whereby freshlyformed concrete blocks or stones carried by the shelves will be thoroughly impregnated j with the steam and hardened and seasoned in l a short period of time. The frame of tubing or piping 20 is provided with a plurality of j apertures 22, which are formed to project the steam passing into the frame to the center of a car, thereby insuring a positive distribution of the steam throughout the entire compartment of the car.

As described in one of the above-mentioned applications, particularly the process of manufacturing artificial-stone buildingblocks, Serial No. 297,168, the cars are loaded with freshly-molded stones or blocks and are closed and moved into a suitable buildj ing, where their connections 19 are connected to pipe-lines arranged between the tracks upon which the cars travel. The pipe-lines stones contained Within them are thoroughly j hardened and seasoned and have waterproof qualifications which permit them to be used for practically all building purposes.

From the foregoing it will be observed that my invention in its broadest aspect embodies a car for seasoning and hardening concrete blocks or stones, and in this connection I do not care to confine myself to any specific type of car otherwise than a tight compartment in which stones or blocks may be placed and subjected to the action of steam. In lieu of steam I may use water or a similar liquid for thoroughly seasoning blocks placed in my improved cars.

What I claim, and desire' to secure by Letters Patent, is`

A car of the type described comprising a body, shelving arranged within said body, a steam connection carried by said body for conveying steam to the interior thereof, a rectangular framing of perforated pipes supported on the bottom of the car, said framing being in communication with said steam connection and arranged that one or more of the perforated pipes lie directly underneath each shelf in the car, substantially as described.

In testimony whereof I aflix my signature in the presence of two witnesses.
